Available components
How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. How we score → Why this is hard to score →
Supply Chain Security98
- No malware found by supply-chain analysis.Pass
- No known CVEs affecting this package version or its production dependencies.Pass
- No install/post-install scripts declared.Pass
- 31 of 96 dependencies flagged as unhealthy. View diagnostics → Partial
Provenance & Transparency100
- Source repository is publicly reachable at the declared URL. View diagnostics → Pass

- Actively maintained (last published 15 days ago).Pass
- Publishes a security disclosure policy (SECURITY.md).Pass
Schema Quality & AI Usability66
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 549 tokens (~183/item across 3 items; 3 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management77
- Stability observed for 23 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage90
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 71% of tool parameters carry a description.Partial
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 3 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 4 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
How do I install the Codex Delegate MCP server?
Codex Delegate runs locally as an npm package, launched with npx -y codex-delegate-mcp. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
cancel ~100
Cancel active runs. delegationId selects one (announced in progress before spawn — the only handle if a run wedges at startup), threadId all on its thread, neither all. Waits for settlement; if a process tree survives the kill deadline, it still returns and the delegate result warns. Status: cancelled, nothing-active, or not-found (no active run with this ID).
| Name | Type | Req | Description |
|---|---|---|---|
| delegationId | string | – | – |
| threadId | string | – | – |
No output schema declared.
No examples provided.
delegate ~337
Delegate a coding task to OpenAI Codex. Never run codex from the shell — use this tool. Check status before trusting result — a run that spawns then fails returns normally. Keep model, reasoningEffort and fast at their defaults unless the user asks. See the delegate skill.
| Name | Type | Req | Description |
|---|---|---|---|
| fast | boolean | – | Codex Fast mode; higher credit use. |
| mode | string | – | agent implements; plan returns a structured plan; ask answers; review runs native review. |
| model | string | – | Codex model id: gpt-5.6-luna, gpt-5.6-sol, gpt-5.6-terra, gpt-5.5, gpt-5.4, gpt-5.4-mini. |
| reasoningEffort | string | – | minimal is rejected by every published model; none is accepted though the catalog omits it. |
| resumeThreadId | string | – | Thread to continue. Reuse its workspace. Forbidden with review. |
| reviewTarget | – | – | Required in review; forbidden otherwise: uncommitted, base branch, or commit. |
| spec | string | yes | Brief with goal, scope, fixed decisions quoted exactly, and acceptance criteria; reference files instead of pasting code. |
| timeoutMs | integer | – | Whole-run cap in ms (default 1h). Mid-turn silence is allowed; startup has a separate 60s first-output deadline. |
| webSearch | boolean | – | Codex's built-in web search. |
| workspace | string | yes | Codex's working directory; not confinement. Must already exist — never create one for the call. |
No output schema declared.
No examples provided.
doctor ~49
Diagnose plugin/CLI/login, recursion, and workspace (default: server cwd). deep adds no-quota help and model-catalog checks.
| Name | Type | Req | Description |
|---|---|---|---|
| deep | boolean | – | – |
| workspace | string | – | – |
No output schema declared.
No examples provided.
